Shut-off valve GLO Fig. 215 DN20 PN16, gray cast iron EN-GJL-250, construction: 31, swing check type, loose disc with spring, stem, disc and body ring – stainless steel 215A020C31

The ZGLO Fig. 215 shut-off valve is a reliable solution for flow regulation in diverse installations. Manufactured from gray cast iron EN-GJL-250, it ensures long-term, trouble-free operation even under demanding conditions. The design features a loose mushroom with a spring, while the stem, mushroom, and body ring are made of stainless steel, guaranteeing resistance to corrosion and high pressure.

This valve is suitable for hot, cold, and cooling water systems, as well as steam systems, industrial processes, district heating, and power generation. It complies with the Pressure Equipment Directive 97/23/EC and carries the CE marking for DN 32, confirming conformity with European safety standards. Designed for use with liquid media, including water and steam.

• Robust construction: Body made of gray cast iron EN-GJL-250 provides resistance to mechanical damage and corrosion.
• Corrosion resistance: Internal components—stem, mushroom, and body ring—made of stainless steel extend valve life and minimize failure risk.
• Wide application: Ideal for water systems (hot, cold, cooling), steam systems, and industrial and power applications.
• Safety: Compliance with Pressure Equipment Directive 97/23/EC and CE marking (for DN 32) ensure safe operation.
• High tightness: Leak-tightness class A per EN 12266-1 ensures minimal medium loss and reliable performance.
• Compatibility: Technical data is available in popular calculation software libraries: Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5—facilitating system design.

The valve features a simple design and easy installation thanks to drilled flange connections compliant with EN 1092-2 for body material A, and installation length conforming to EN 558-1 Series 1. The handle enables manual operation, while the spring in the mushroom ensures secure closure and tightness. This is a robust, proven design providing reliable flow shut-off in the system.
